SPECIFICATION. forming part of Letters PatentgNo. 265,166, dated` September 26, 1882.

Application tiled March 1882. (No model.)

To all whom it may concern Be it known that we, THOMAS L. SMiTHand WILLIAM S. DOIG, of Brooklyn, county of Kings, State ot' New York, have invented a new and useful Improvement in Nail-Feeding Machines, which is fully set forth in thc annexed specification and drawings.

Our invention relates to that class or" naili'eeding machines which are used on box-nailingmachines. Our object, therefore, is tofeed one nail only for each punch at every revolution of the machine, and to arrange its mechan ism so that it will work automatically and more positive than any device heretofore made, the same being hereinafter-more fully described, reference bein g had to the accom pau ying drawings, in which- Figure 1 represents an elevation ot' nail-feeding machine on section y y, Fig. 2, mounted on the top of the frame of a box-nailing machine. Fig. 2 is a plan view of nail-feeding machine. Fig. 3 is nail receptacle or reservoir on section ma', Fig. 1. Fig. 4 represents an enlarged view ot' the disk-cam in plan and elevation. Fig.5 is an enlarged view of spring-stop. Fig. represents an enlarged view, showing plan ot' springs being operated upon by the disk-cam.

Fig. 7 represents a modiiication ofFig. 6.

Similar letters referto similar parts throughout the several views.

A represents the upper portion of a box-nailing machine, upon' which the bed B of nailfeeding machine is mounted.

C is an upright for supporting the incline guide or track plate D.

E represents shaft to which disk-cams F are secured, and are operated by a pawl and ratchet, h, which is attached to the cross-head T of the machine by link l.

Gr is a nail receptacle or reservoir, which is hinged to the upper end ot' the track or guide platesD at a.

H is a cam for imparting a tilting motion to the reservoir Gr. f

I is a spring-stop, which closes the orifice or channel b between the plates D, and is secured under the track-plate, as shown at 0, Fig. 2.

K is a spring-pointer, which regulates the movement of the nails.

To operate the machine the reservoir G is partly iilled with nails while it is in the positionishown bydotted lines in` Fig. l. Then,l by the revolving ot' the cam H, the reservoir Gbeing hinged at a to plates D, it will be raised to a corresponding incline with said track D and allowed to remain iu that posi tion a short time by the dwell P on cam H.

and while in this position the nails will fall I forward or down toward the side d, in which are slots or openings e, as shown in Fig. 3, suf- 6c,

ciently large to allow of one nail-head to pass through. The bottom ofthe reservoir also has openingsj'to admit the body'of the nail. VThe projections g facilitate Vthe distribution of the nails over the slotsf. When the nail has dropped into the slot or openingf it Slides down the incline in oritice b, being supported by the head upon the track or guide plate D until it is arrested by the stop-springl, which is so formed as to close the channel b, and the 7o same being made the reverse angle of the in`- eline track D, as shown in Fig. 5 at q, for when the nail is arrested one side ot' the head rests upon this incline q, thereby causing the point..

ot' the'nail to be thrown forward and opening 75 the space between the rst and second nails for the pointers K, the shaft E being revolved by the pawl h and connecting device. The disk-cani F, being secured to said shaft E and moving with same, causes one of the teeth or 8o projections M to press the pointer K forward between the first and second nails, (marked s s in Fig. 2,) and continuesto move the same forward until it has forced the stop-spring I hack from over the orifice b, as shown in Fig. 6 by 85 dotted lines, and allowing the nail s to drop into the tube N, thence to the punch. The nail s2 is retained in the channel by the point K until the same is released by the revolving of the disk F, when it will spring into its for- 9o mer position, as shown by dotted lines, Fig. 6. The point K is secured to the upright G by having the shank a threaded and lock-nuts on both sides, thereby enabling the same to be adj usted to suit different-size nails. 'lvhe point 9 5 a. It' by accident the point K should strike 10o the nail, to prevent breaking the same or damaging other parts of the machine, we place a coil-spring, R, around the shaft E, as shown in Fig. 2, which allows said shaft and disks to recede; butthespriugisofsufcientstrength to perform the Work required. Thus it lwill be seen by this device that we have a very siniple, durable, and positive-Working machine, as it will Work aecuIately with any kind ofv nail.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In a nail-feeding machine, the combination of the inclined plates or guides 1) with spring-stop I, the foot or stop q, the springpointer K, and disk-cam F, substantially for the purpose set forth.

2. In a nail-feeding machine, the combinati0n,withinclinedplatesorguides D,of' the tilt- THOS. L. SMITH'. NVILLIAM S. DOlGr.
